if I'm not mistaken, APX is made by Procaps in canada, which makes DXS, which GI just bought. I have APX paintballs with half the shell reads DXS and half shows the APX logo. So basically it comes down to Valken, PWI, Kee and Procaps. Hate to say it, but the Chinese company PWI gets the gold star in my book, although I do love me some APX.
